s. HlL ANb CABLE CLAMP Filed Nov. 6, 1928 Patented Oct. 3, 1929 SVERRE HILLANID', F BROOKLYN, NEW YORK CABLE CLAMP Application filed November The object of my invention is to provide a clamp of this class which may be used with cables which are to be connected one with another or with cables used for truing buildings where the steel frame work has to be correctly positioned from time to time during the process of erection so that it may go up true. This object is accomplished by my invention, some embodiments of which are hereinafter more particularly set forth.

For a more particular description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in which Figure 1 is a side elevation of my improved clamp ready to be applied in truing a building or for any other similar purpose.

Figure 2 is an enlarged sectional view of the clamp and connected parts.

Figure 3 is a sectional view, taken on the line indicated by 33 of Figure 2, looking in the direction of the arrows.

Figure 4 is a plan view of a yoke.

Figure 5 is a perspective view of one of 95 the clamp members.

Figure 6 shows a modified construction suitable where it is desirable to connect the ends of two cables without a splice.

Throughout the various views of the draw ings, similar reference characters designate similar parts.

In the structure shown in Figures 1 to 5 inclusive, my improved clamp 1 is composed of a horseshoe bar 2 bent so as to form a loop 3 with converging ends a, as indicated. Near their free ends, the bars 4 are notched at 5 so that they may spring outwardly and engage a yoke 6. as shown. The holes 7 through which these ends 4 pass are made a little larger than the diameter of these ends so that these ends may be sprung together and then the yoke 6 may be removed or restored, or both, as desired. It will be observed from Figure 4 that the yoke 6 passes on one side only of the cable 8 which will be referred to below.

The ends 4 also carry the clamping members 9 and 10 which slide freely thereon and are connected by a metal dowel 11 which is fixed to the clamp member 9 and slides free- 6, 1928. Serial. No. 317,663.

ly in a suitable perforation in the member 10, as indicated in Figure 3. The holes 12 through which the ends 4 pass are larger in diameter than these ends and are adapted to slide freely therein. The inner ends of the clamp members 9 and 10 are provided with grooves 13 which are roughened, as shown in Figure 5, so as to form surfaces which are adapted to firmly grip the cable 8 which may be passed between them.

The loop 3 may be passed through a corresponding eyelet 14 of a turn-buckle 15 when. the clamping members 9 and 10 and the yoke 6 havebeen removed from the ends 4. A Thereafter these clamping members and the yoke may be restored to the position indicated in Figures 1 and 2. When this has been done, thecable 8 may be placed over th yoke 6 and through the recesses 13 while the cable is held by hand in position. Thereafter the clamping members 9 and 10 are slid in the direction of the yoke 6 and, when in position, are tapped by a hammer or similar instrument until they bin-d firmly. Once they bind firmly on the cable 8, they fix the cable in relation to the clamp 1 so that it will not move until released. Thecable may be released by tapping the clamps 9 and 10, either or both,-so as to drivethe same in the direction of the loop 3 and thereafter the cable may be removed free of the clamp, as is obvious.

' It is also obvious that the cable 8 may be provided at one end with a loop 16 and a hook 17 corresponding to the hook 18 which forms a part of the turnebuckle 15. These hooks may be secured to any part of the metal frame of a building so as to plumb the same in the conventional manner. i

It will be observed that in the practice of my invention, it is unnecessary to reeve a cable through a loop 14, as has heretofore been the custom and then secure the loop by means of a clamp. Such is very objectionable because not only of the trouble incidental to passing the cable through as indicated, but

also because the sharp bend in the cable brakes the same as to some of the strands thereby making the cable a difficult thing to handle and the bends cannot be straightened out so that it is impossible to coil the cables true. As the cables cannot be cut, it is sometimes necessary to pass long lengths through a loop 14 before the proper point is reached where the loop is to be made. When my improved clamp is used no loop is made in the cable and the clamp may be applied anywhere. Furthermore, it can be set up and removed with no other instrument than a bar or a hammer and it functions without nuts or bolts. 1

In the foregoing has been described a structure wherein the loop 14 is a part of the turnbuckle 15. Obviously, the loop 14 could be like the loop16, if desired, that is a portion of a cable without in any way changing the functioning of the clamp.

At times, it is desirable to connect the ends of a cable for temporary purposes. Then this is desired. the structure of Figure 6 is employed. Here there are two sets of clamping devices 9 and 10, two ends of cables 8, two yokes 6 and two bolts 19 with their ends bent to converge and the extreme ends are screw threaded to receive nuts 20, as indicated. The cables 8 are inserted or detached precisely, as above described, and when in place, as indicated in Figure 6, they are firmly held.

WVhile I have shown and described some embodiments of my invention, it is obvious that it is not restricted thereto, but that it is broad enough to cover all structures that come Within the scope of the annexed claims.

Having thus described my invent-ion, what I claim is:

1. A cable clamp having connected and converging bars, a yoke mounted near the free ends of said bars and connected clamping members slidably mounted on said bars and adapted to be drawn together whenever they are shifted towards the yoke.

2. A cable clamp having connected and converging bars, a yoke connecting the free ends of said bars and a clamping member having a cable receiving port-ion between two slid ably mounted and connected members, one sliding on each of said bars.

3. A cable clamp composed of two converg ing bars, a yoke mounted near the free ends of said bars, means for uniting the other ends of said bars, a clamping member slidably mounted on said bars and provided with cable gripping means and a guiding dowel connecting said gripping means.

In testimony whereof, Ihave hereunto set my hand this 3rd day of November, 1928.

SVEIRRE HILLAND.
